6.3 Logger Interface

While the Router module of FCM is loaded, the user may load the logger component of FCM. This is a standard Linux user-space application. The application will display one line upon loading. The line will display the program's name and version. Further messages will not be displayed. The following arguments will be accepted, and all must be given, in any order:

  1. -d time or -duration time
    The duration of the logging, specified in seconds
  2. -i time or -interval time
    The interval between records produced in the output file
  3. filename
    The filename which should be used for logging. If a file exists with this name already, it will be overwritten.
